Abstract
One embodiment of the invention is directed to a data processing system that includes an electrical detection circuit to determine whether the electrical power is going from “on” to “off,” or changing from “off” to “on;” a peripheral device, including a processor to calculate the amount of electrical energy required for the peripheral device to perform a task; a task queue for the peripheral device that can be read to find a task if the electrical power is going from “on” to “off;” and a non-volatile memory, including a task queue to store data describing the task if insufficient electrical energy remains available to the peripheral device to complete the task.
